you can use :if

before_save do_something, :if => Proc.new {|model| model.some_boolean_attr_or_method }

or simply

before_save do_something, :if => some_condition

Rails 5

I've had success defining a private method 5 which contains the boolean logic and then 4 passing it as a symbol (that last part seems 3 like a requirement):

before_save do_something, if: :private_boolean_method?

I also recently found 2 out you can simply pass a block (took me 1 a while to figure out the syntax):

before_save do_something, if: -> { condition == "met" }
